    Could be that they don't want to stress the power assembly too much. I imagine most would want to slap a custom block on this and overclock, but it depends on how strong the VRM's are. Similar to the 780/Titan issue of the VRM's being a little less than ideal for 1300+ OC's on the reference cards. Granted it was achievable, but too much power through those puppies and they were liable to pop. Not so sure how a dual chip VRM assembly would deal with the intense TDP, stress and overall heat. It wouldn't surprise me to see a voltage limit on this.

    Agreed, it looks like they tried to copy the "premium" styling of the GTX 690/Titan/Titan Z, but the end result ended up looking like a cheap knockoff.

    Well, unless you have a scarcity of PCIEx16 slots, chances are you'd be much better off with a couple of 290's or 290X's if the $1500 price tag is to believed. I'm pretty sure you could grab two cards, full cover blocks, fittings, and a Crossfire bridge if required for less than the price of the 295X. They will overclock better, and hooking them up to a triple rad gives the option of using less aggressive (noisy) fan profiles.

    If the 7990 is anything to go by, two single cards appears to be better than dual GPU single cards.

    Can probably be a reasonable generalization levelled at most dual GPU cards.
    The 7990 (initial pricing), this card, and the Titan Z aren't even attempting to achieve price/performance parity with a couple of single cards. At least previous duallies made an effort not to charge a premium over two single GPU boards. Add in the fact that a duallie is generally either lower performing or louder/hotter (or both) than two single cards and I can't really see the attraction for a gaming workload.

    The VRM on this seems to be a doubled up and more compact version of the R9 290X VRM so the GPUs can easily get fed 375A each so 750A total current allowance. Just don't expect the PCIe 8Pins(30A-40A) to be able to carry that much power(750A @ 1.5V = 1125W = 93A @ 12V) so if you do plan to use all of the VRM's capability you should solder on 1 or 2 more 6 pin connectors or risk burning something. So VRM wise your good but the dual 8 pins are insufficient. Most Quad R9 290X OC attempts I've seen included 2 1600W PSUs so this card OCed + OCed intel hexa core/ AMD octa core will need a 1200W+ PSU.

    I remember I could overclock the 6990 up to 1.35v on both cores with Trixx, yielded me 1100 Mhz which was insane on that card, ATI has always had beefy PCB components, they actually care!

    Hagedoorn, Hilbert, AMD Unveils FirePro W9100, Guru3D.com, 3/27/2014.
    http://www.guru3d.com/news_story/amd_unveils_firepro_w9100.html

    GTX Titan-Z SPP = 8.06 TFLOPs. = 700 MHz per GPU = 2x 6GB VRam = $3,000.00 per unit.
    R9-295x SPP = 11.466 TFLOPs. = 1018 MHz per GPU = 2x 4GB VRam = $1,500.00 per unit.

    64bit floating point precision comparison:
    GTX Titan-Z 64FPP = 2x 1.3468 TFLOPs at stock.
    K40 Tesla 64FPP = > 1.4 TFLOPs. = 12 GB VRam = $5,400.00
    FirePro W9100 64FPP = 2.56 TFLOPs. = 16 GB VRam = $3,000.00 to $4,500.00
    R9-295x 64FPP = 2x 0.716672 TFLOPs.
    R9-290x 64FPP = 0.704 TFLOPs.

    What do you want to bet W1z is testing the 290x2 under NDA as we poke around in this thread ;)

    Here's his 290x CF review perf chart (scaling isn't great, but then again who knows what new drivers have done for it):

    We can only hope! Can't wait to see the eventual comparos to the TitanZ.

    It’s disappointing the use of pretty much standard pump/blocks that aren't even independent (first one heats the water and sends it to the next). I really had hoped AMD had stepped up their game. Engineering something more akin to a vapor chambers that wicked the heat quickly from the chip, then to a larger area permitting the water block not to have such a localized hot spot. A single pump that’s more integrated into the radiator/fan module and then two line in/out but split to send cool water to each block independently. I think if done right you could have exceptionally good heat transfer in a smaller package blocks with less restriction, necessitating just one pump and perhaps able to better juggle the radiator/fan requirement, somewhat…

    While overall outward aesthetics is a little blah, and mimic’ie of the Nvidia style. I think AMD/Asetek should have taken it to another level of refinement and not just pulled on what just the existing ROG ARES II ASUS used. Asus if I remember made a limited run of 1,000 units of ARES II, selling them at $1,500. AMD easily is probably looking at minimum 5x that, and they can’t price it better on their volume.
    Not my cup of tea.

    Woah, I didn't realise crossfire scaling on the 290X was really that bad... I expected a litte more than 31% overall...

    considering thats over 1600 x 900, 1920 x 1080 and 2560 x 1600 its not that bad, the scaling goes up a little at 2560 x 1600 to 47 %, guessing its even better at 4K

    I think, and I really want to believe, the 295X2 will beat the Titan Z. The Titan Z will be voltage locked, and it will be bottlenecked by the air cooler. The AMD however will have a much higher thermal tolerance before throttling (i hope), and will possibly have a higher voltage perimeter.

    All that being said. Titan Z is not designed for gaming, for the 50th time, it's a cheap dpcompute card for home servers. This needs to be stapled to every forum header, title, post, thread, the whole works, until everyone on the internet understands that.

    Yeah it needs more pixels to push, seems cpu bottlenecked at lower res.

    Why do you say so? Nvidia themselves says its for gaming.

    They also target the professional markets. In fact, the Titan Z was announced at a technology conference, not a gaming event, and the CEO specifically mentioned the professional aspects of the board in his launch introduction


    So if you had a product that was proficient in more than one market segment, why wouldn't you market the products for those markets ?

    AMD pushes cryptocurrencies on its gaming blog, are we to assume that Radeons are mining cards only?
    Of course not. You market wherever you have an opportunity to sell.

    If Nvidia designed the Titan Z for gaming why would they pay RCoon to say otherwise?

    Logical thought process escapes random forum poster - No headline news ever.

    295x2 just has to a better Price/Performance then Titan Z/790 = Win

    We should know when the 295x2 will launch on the 8th

    Anyone know when the Titan Z will be launched ?

    If you are right about Titan Z, its Geforce tag is just a cunning marketing trick then. Crap for nVidia.

    Well, that just sounds stupid.
    Buying high end performance isn't about AMD vs Nvidia, it's about performance, and maybe performance per dollar.
    People aren't going to buy the 295X2 because it's "better" than another overpriced card that few would actually buy for gaming. What they are going to compare it to is a comparable solution.

    R9 295X2 = $1500

    2 x MSI 290X Gaming = $1180

    and if you already have an interest in proper watercooling- as a prospective buyer of watercooled $1500 graphics cards should be

    2 x PowerColor LCS 290X's = $1400

    or if you're not lazy, you can save yourself $46 by doing it yourself

    2 x PowerColor PCS+ 290X's = $1140 + 2 EKWB FC blocks $214...Total: $1354

    Better overclock than the 295X2. Better power load distribution ( 4 PCI-E inputs versus 2). Less LED lights. Lower price.

    The reality is that people go where the performance is at this level of expenditure- and performance (and price) resides with combinations of single GPU boards, not some PR grab for the halo which might (or might not) give midrange card buyers a chubby.

    You really sound like someone that has never bought enthusiast grade hardware.

    Since your reverting back to single gpu card argument in a dual gpu comparison does that mean you've given up hope already. At least wait for the reviews.

    It just has to win the dual gpu card war and since Nvidia is selling Titan Z as a Gaming/CUDA Compute card it will compete on a dual GPU card basis with it. No matter how much you and others try and defend or move the goal post in your heads.

    Does anyone hear that? Its HumanSmoke in another AMD thread.
